### 4/5 — Needs more Content

*2025-07-27*

The game is fun but would be nice have a versus mode or option for larger board. Also ability to unlock different backgrounds and card colors.

### 3/5 — Good, but...

*2025-02-06*

...the cards don't flip quickly, and they don't close after they have been selected. The game becomes slow and unwinnzbke due to the lethargic cards when there are no matches in the first 6-8 cards. As there are only ten matches, if the cards don't flip back the game becomes almost unwinnable at the fastest speed-30 seconds.   Other than that, pretty good.

### 5/5 — Cards :)

*2024-09-23*

This is wonderful how the cards have animated turns. These move at a pace that is not displeasing, such as being not too fast or slow.
